Expectations met

Review by Kevinon 11/17/2018

Well, it has been over a month and she is working perfect. full bath with kitchen AND DISHWASHER. winter is here AND she is set with the additional burners on. had to tweak a bit, but running steady at 125 output (like hot showers). I do have a 1.5 gallon limit shower head but with really good city water PRESSURE. Have a 71000 BTU rated gas feed line TO THE unit and no issues with furnace and unit running at the same time. My old tank was 40 gal rated at 33000 btu total output and does not even come close to what this unit can output. One thing I would like to see is RECOMMENDED MAINTENANCE in the manual... I'm going to descale with distilled vinegar on the time changes each year and blow out the heat exchanger with canned air once a year.

Space saver

Review by Smw1986on 11/12/2018

I got this instead of a typical water heater after a lot of research. The old one had leaked twice and damaged the floor underneath a lot, making it a worry to put another heavy piece there. Since I'd been interested in a tankless, this was great timing in a way. Easy to install, works well in our small home, and only took a few quick adjustments to get the temperature right for us.

Review by Kevinon 10/16/2018

REplaced a 40 Gal tank water heater.

would recommend instructions on how to adjust heat output in the how to use booklet. on line instruction good, but if internet is down would have had to go old school. the recommended installation kit i purchased was the wrong size so my plumber had to buy extra parts to make it work. overall i like it and am very pleased. only been using for a couple of week, but water is hot and continuous!

Great unit, great price, great company!!

Review by Janon 3/18/2018

I purchased the 10L natural gas unit (with display panel - which is well worth the few extra dollars). I was replacing a 40gallon tank unit that was leaking. I decided to go tankless to free up space in my garage. I called around and discovered that I would have to pay $6000 (to increase the size of my gas line) or $5-7000+ if I wanted an electric one (to put in a 220 line and upgrade my electric panel. I did some more searching and found Marey.com (same size gas line as mine & battery ignition). I ordered it direct from Marey and it arrived sooner than expected. I made one run to Home Depot for ducting and lines (and a few odds and ends). A few hours later and 'voila' all the hot water I need for less than $300. I'm super pleased with my purchase and highly recommend both the unit and Marey!!! The only puzzle is that I can't seem to remove the small filter screen that is supposed to be cleaned from time to time (I'll call Marey one of these days).

Here's the punch line: I'm a 72 year old woman who installed it all by herself :) :)

Review by coryon 5/21/2017

purchased through home depot, did a self install/conversion from 40 gallon heater and everything went extremely smooth and works great. one of the silver turn knobs was broken upon arrival and I am trying to figure out how to go about getting a new one (water flow control knob-plastic). other than that, I am extremely pleased with my purchase, and will be heavily considering another marey brand unit when I upgrade mine to a larger size unit that will more suit my household - home built in 1962, 1.5 bath, dishwasher, laundry, etc.

Good and Cost effective but may require some fiddling with to make it work with things that use low amounts of water

Review by Ianon 4/25/2017

It works well. As many people have said though it requires a little adjusting to if you were previously using a Tanked water heater.

If you have faucets or equipment that is energy efficient or uses low water. This unit will probably require some adjusting to make it work. But customer service was very helpful with that.

Also if you are using this in an older house it might require some adapters for use to older pipes.

Overall this is a good unit and seems to work great so far and does not run out of hot water if you are using it constantly. I would recommend it even if it took some adjusting to to make it work correctly at first.

Review by friscodebon 3/15/2017

we absolutely love our tankless water heater by marey! my husband bought our first one a few years ago at home depot, and thought that the bigger, more expensive heater would be best - boy, was he wrong. we could never get it adjusted correctly to produce hot water anywhere in the home (part of this i think was our water pressure) our new marey water heater is just perfect and provides hot water anywhere we need it. my husband did mention that with all of our water-efficient faucets, he did have to make a few adjustments on the unit (water metering valve) to keep the water hot at different areas of our home (he said that the 2:00 position worked best for us) . we couldn't be more pleased with our heater and will recommend it to everyone. thank you marey!

I WILL NEVER INSTALL ANOTHER TANK TYPE WATER HEATER. THIS THING PUTS OUT HOT WATER WITHIN A FEW SECONDS, TURNS ON AND OFF AS SOON AS THE WATER STARTS OR STOPS FLOWING.

Ordered with home depot. unit was ordered on 09/09/2016, shipped on 09/12/2016 and put in service on 09/16/2016. installation was fairly easy but the unit would not stay lit initially. the TROUBLESHOOTING guide was not very helpful. through trial and error, i found that by reducing the water setting, i was able to get the unit to operate properly. i replaced a bosch ng tankless water heater that was 12 years old and used pilot light ignition and i am hopeful that this marey unit will be more reliable and as ECONOMICAL.

The installation of the Marey product was an easy process.

Compared to the price, the unit matched my expectations.

Had my handyman install the water heater. and it took a couple days. He had to refit the in and out water pipes and change the exhaust duct to 4" plus mount the unit. It took several minutes to get the unit to function properly but that was because of a water pressure regulator that was on the input line. After removing that the unit functioned as it should. Very happy with it.

Hello, I purchased a 10L NG DP about 14 months ago, my only problem is battery changing issues. I was wondering if you have a conversion kit that you sell that will change from battery ignition to 110 v plug in.

We do not have a conversion kit to go from battery activated to 110v power cord.

Just had one installed in basement, seems to work well. Two questions- 4 inch vent was reduced to 3 inch and connected to old water heater vent, 3 stories up chiminey, is this ok? unit shuts itself off occasionally, why?

Because of the higher BTU rating it is never recommend to down size the required venting. Also, if the vent pipe is going to exceed 60 inches in total length it is recommended to use a low CFM booster as indicated in the manual. If the heat does not dissipate from the fire box as quickly as it is supposed to this could cause damage to the unit and could also cause the over heat safety sensor to engage and shut the unit down. For more information or for further trouble shooting please email us directly atcustomerservice@marey.com.

In the 16L power NG Q/A portion your respond that it needs a 3" vent. What size vent is needed for the 10L power NG? I am looking to replace an tank water heater that had a 3" vent that went to shared chimney with the furnace. Is this ok?

The battery operated 16L unit uses a 5 inch vent, the 10L battery operated unit uses a 4 inch vent and the 16L ETL (110v power cord) uses 3 inch vent. It is never recommended to down convert the venting size, how ever you can up convert. In the installation manual it also mentions that if the overall vent length is going to exceed 60 inches in length then a low CFM booster may be required.

The discharge valve as a whole can be removed from the water valve assembly. Turn off the water supply to the unit before removing the discharge valve. Just simply grip the post with your fingers and unscrew it. At the top where it screws into the water valve there is an o-ring that could be damaged, thus causing the drip. The second reason is if you look at the bottom of the discharge valve you will see a bleeder type set screw. This is what allows the discharge valve to act as a high pressure release. If this set screw is set too low then the unit will drip. Use a #1 flat head screw driver and tighten it up a couple of turns, until it is about 1/3 up the post.

where do i install the condensation drain on the portion of pipe outside of struccture on pipe and what is a condensation drain?

Question by: shirley adler on Oct 5, 2017 8:27:00 PM

The condensation drain is usually the first piece of venting material that attaches to the heater. This is to drain condensation from the vent pipe. Other than some basic guidelines we do not have anything to do with the venting. For additional venting questions we recommend you consult an HVAC professional.

I have a Gas 10L NG DP that is still under its first year of warranty. I am currently experiencing a big problem with it. The digital display is always on, even when no water is flowing through the water heater. Also it tries to ignite for about 10 seconds as soon as i replace the batteries. If the water is running at that time it will ignite and work. But as soon as i turn the water off, it will not try to relight when the water is turned back on. It seems that it cannot determine the water flow rate. Please help!

It sounds like your microswitch is not closing all the way to fully disengage the unit. Usually this is a sign of build up in the water valve assembly. If you have not done so already it may be time to flush the unit with vinegar. We also have several trouble shooting videos on you tube that will help identify the problem.

Todat this heater started flooding . Water was running all over the place. The unit had water all over the Inside of the unit. What would cause this? The unit is less than 1 year old.

Usually when we see this during the winter it is the result of weather related freeze damage depending on your geographical location. If the unit is not drained between uses when the outside temperature is below freezing cold air can come down the vent pipe and freeze the water in the top of the heat exchange. We typically ask for photos showing where the leak is coming from so that we an asses what might have caused the leak. Please send photos to customerservice@marey.com.
